Hydroxyalkyl amides as fungicides to eumycotina in phanerogamia plant life

Abstract

This invention relates to the control and/or eradication of Eumycotina type fungi is phanerogamia plants with one or more of the substituted carboxylic amides having the formula: ##STR1## wherein A is an organic radical of from 2 to 14 carbon atoms and is selected from the group consisting of hydroxyalkyl, hydroxyalkoxy, haloalkyl radicals and substituted alkylether radicals having the structure --R 1 --O--R 2 --, where R 1 is alkylene of from 1 to 6 carbon atoms and R 2 is alkyl of from 1 to 6 carbon atoms substituted with a hydroxy, carboxylate or halocarboxylate group; and wherein R is an acyclic alkyl radical, an alkenyl radical having one or more doubly bonded carbon atoms, a mono- or di- fluorinated benzyl radical or a mono- or di- chlorinated benzyl radical, said R radical containing from 4 to 20 carbon atoms. The invention also relates to a method of using a fungicidal amount of said carboxylic acid amide or carboxylic amide mixtures on phanerogamia plants for control or eradication of Eumycotina infection.

What is claimed is: 
     
       1. A process for the control of Eumycotina fungi which comprises applying to a plant a fungicidal amount of one or more amide fungicides having the formula: ##STR16## wherein A is hydroxyalkyl containing from 2 to 14 carbon atoms and is and wherein R is an organic radical of from 4 to 20 carbon atoms and is selected from the group consisting of an acyclic alkyl radical, an alkenyl radical having one or more doubly bonded carbon atoms and a mono on di-fluoxinated benzyl radical. 
     
     
       2. The process of claim 1 wherein the fungicide, in a concentration of from about 25 ppm. to about 2,500 ppm is applied in a liquid composition in an inert liquid carrier. 
     
     
       3. The process of claim 2 wherein the concentration of the fungicide in the carrier is between about 30 ppm and about 800 ppm. 
     
     
       4. The process of claim 1 wherein the fungicide in a concentration of from about 25 ppm to about 2,500 ppm is applied in an inert solid carrier. 
     
     
       5. The process of claim 4 wherein the concentration of the fungicide in the carrier is between about 30 ppm and about 800 ppm. 
     
     
       6. The process of claim 2 wherein the fungicidal composition is applied to the plant at a rate of between about 0.5 and about 30 pounds per acre. 
     
     
       7. The process of claim 6 wherein the fungicidal composition is applied to the plant at a rate of between about 1 and about 10 pounds per acre. 
     
     
       8. The process of claim 2 wherein the fungicidal composition is an aqueous emulsion and contains a nonaqueous solvent and an emulsifying agent. 
     
     
       9. The process of claim 2 wherein the fungicidal composition is a liquid dispersion in water. 
     
     
       10. The process of claim 1 wherein R of the amide contains from 8 to 18 carbon atoms.
